Prometheus Can Downgrade iOS 9.3.5 to iOS 9.3.2

Not long back, Apple released iOS 9.3.4 to patch up PPHelper jailbreak and, just a couple of weeks later, iOS 9.3.5 download to patch up some very serious security issues that affected all iOS versions and could result in data and security being compromised. Anyone who has updated to either of these iOS versions has lost the chance to jailbreak because Apple is no longer signing iOS 9.3.3, the latest version that can be jailbroken.

We used to be able to use a package called TinyUmbrella [ext link] to save your SHSH blobs, enabling us to downgrade to a jailbreakable version of the iOS but, at the moment, TinyUmbrella is not able to do this. However, thanks to a video that has been released today, there is a glimmer of hope for the future in the guise of a tool called Prometheus.

The video was uploaded by a hacker called @tihmstar [ Twitter ] and shows Prometheus working partially to Downgrade iOS 9.3.5 back to iOS 9.3.2 on an iPhone 5s. The video shows the downgrade successfully completing meaning that the iPhone can now be jailbroken with PPHelper.

Downgrade Requirements :

At this stage, we don’t have sufficient information to hand to tell us the requirements of using Prometheus but the developer has said that use of it will depend on APTickets and a number of other conditions that he hasn’t finished working out just yet. APTickets are a newer form of the SHSH blob and can be used in the same way, to downgrade your iOS version provided your tickets have been previously saved.

Release Date :

We don’t know when Prometheus [ext link] is going to be released and, as it is still being developed, we can’t see it being in the very near future. It is also a complicated tool to use and full guidance will need to be issued as well. However, if Prometheus does turn out to be the real thing and is released when finished, it will be the first tool of its kind to help 64-bit devices downgrade back to earlier versions of the iOS firmware.

For now, if you are using the PPHelper jailbreak on your iOS device, stick with it and do not update beyond iOS 9.3.3. If you do, you will lose your jailbreak and will not be able to reinstall it until a new utility is released. That is now likely to be for iOS 10, which is due for release in the next couple of days. If your device is jailbroken, make sure you have downloaded Cydia Eraser as this will help you to restore your device in the event of a problem without affecting the iOS version you are on.
